^^^^^^^Thats a ****ing allen wrench broke off the in the ASA set screw!!!!!!!!

Put tank on it and it felt loose, went to tighten the screw and the allen wrench wouldn't go in. Took a look and some noob used a allen wrench that was a size to small, apparently it got jammed and then snapped off.

The fix:

You know how much I love drilling into a $1800 gun with a $250 anno job

After about a hour of careful drilling with a tiny drill bit I managed to get the allen wrench out with enough thread left on the set screw to be able to use allen wrench to get it out.
